My family and I enjoyed our month-long stay at Kanomping's apartment. It is clean, brightly lit, neatly furnished, well-equipped for our needs and sufficiently spacious for three with two balconies that allow us to work outside when the weather permits. As we were on a business trip, wi-fi speeds were great and we had no problems with multiple online meetings or uploading materials for clients. Housekeeping service was provided each week due to the length of our stay and putting in our request was quick and fuss-free.
There is a concierge at the lobby and the staff were friendly and spoke adequate English. It is convenient for deliveries when we were too busy for groceries or meals outside. That said, it the apartment is conveniently located in Ari and is just a short walk from the BTS station. As there are many office buildings and government agencies in the area, it is safe and the streets are sufficiently lit at night. Convenience stores and pharmacies are just a stone's throw away and there are many cafes and restaurants that we enjoyed around the neighbourhood.
Kanomping and Tatiya were incredible hosts - responsive, helpful and patient with our enquiries and I'd definitely recommend a stay at their apartment when you are in Bangkok!
